Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chemical raw material production, in particular to a feeding device for the production of organic silicon pressure-sensitive adhesive. Background Art
[0002] Silicone pressure-sensitive adhesive is a high-quality pressure-sensitive adhesive with a wide range of uses. It has excellent high-temperature resistance, weather resistance, chemical resistance and electrical properties. It is widely used in automobile manufacturing, shipbuilding, electrical insulation of generators and motors, shielding protection in the printed circuit board manufacturing process, and aerospace fields.
[0003] During its production process, stirring is required in the reactor. The raw materials include solid materials and liquid materials. At present, when solid materials are fed, they are put in through a feeding pipe with a larger diameter and the pipe mouth is sealed. This process requires a lot of manual labor and cannot achieve continuous production. Utility Model Content
[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a feeding device for the production of silicone pressure-sensitive adhesive with a simple structure, a high degree of automation and good sealing performance.
[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:
[0006] A feeding device for producing silicone pressure-sensitive adhesive comprises a feeding pipe, a rotating drum and a storage drum, which are arranged on a reactor cover from bottom to top; the lower end of the feeding pipe is arranged to penetrate the reactor cover, the inside of the feeding pipe is arranged in a stepped shape, the bottom opening diameter is larger than the top opening diameter, a sealing plate is provided on the stepped surface, the sealing plate is connected to a lifting assembly arranged on the rotating drum through a guide rod, a feeding port is provided on the side wall of the rotating drum, the feeding port is connected to the storage drum through a guide pipe, an electromagnetic valve is provided on the guide pipe, a dust cover is also provided on the guide rod, and a pressure relief port is provided on the dust cover.
[0007] In this way, when in use, the lifting assembly drives the guide rod to rise, pressing the sealing plate tightly against the stepped surface to achieve a closed bottom. At the same time, it can ensure a closed environment inside the reactor and ensure smooth processing. During this period, a single material or multiple materials in the storage barrel can enter the transfer barrel. The pressure relief port can ensure that the materials can enter smoothly and avoid pressure differences. When the work in the reactor is completed and the material is changed, the lifting assembly descends and the pre-loaded materials inside it enter the reactor. This solution has a simple structure and can achieve uninterrupted feeding of solid materials in the continuous production process, with less manual participation, reduced labor intensity, and guaranteed production efficiency.
[0008] As an optimization, the lifting assembly is a lifting cylinder arranged on the side wall of the rotating cylinder, and the free end of the lifting cylinder is fixedly connected to the guide rod through a connecting rod.
[0009] In this way, the lifting of the cylinder can complete the unloading and sealing, and the lifting cylinder can ensure the sealing of the feed pipe and ensure the processing quality.
[0010] As an optimization, the sealing plate is configured in a conical shape.
[0011] In this way, when unloading, solid materials can be discharged quickly along the cone surface to ensure the efficiency of feeding.
[0012] As an optimization, a sealing ring is provided on the surface of the sealing plate facing the stepped surface.
[0013] In this way, the sealing effect of the lifting cylinder driving the sealing plate can be guaranteed, and the sealing environment in the reactor can be guaranteed.
[0014] As an optimization, the pressure relief port is externally connected with a bent pipe, and the end of the bent pipe is arranged downward.
[0015] In this way, external pollution can be prevented from entering the transfer cylinder through the pressure relief port during long-term use, thereby ensuring production quality.
[0016] In summary, this solution has the advantages of simple structure, high degree of automation and good sealing. BRIEF DESCRIPTION OF THE DRAWINGS
